There are several ways to disable usually noisy PC speaker in Ubuntu Linux (this is what beeps every time you wish to keep silent). The fastest one is just to unload its kernel module/driver:
sudo modprobe -r pcspkr
Add the the line “blacklist pcspkr” to /etc/modprobe.d/blacklist to turn off the speaker forever 🙂

What, in case where hardware problem occurs? To diagnose a problem we using beep sequence depending on BIOS. Those disabled speaker not supporting such a diagnose?
Thanks so much, I hate the guts of the PC speaker, wakes up the neighbourhood.
Awesome tip, this is one of the first things I do now on a new install.
Newbies might get thrown off by the missing .conf. Here’s the command line method of opening the blacklist.conf file:
gksudo gedit /etc/modprobe.d/blacklist.conf
Really cool tip. Thanks a bunch!
